If there's 4 signs at the front of my shop that say "no food or drinks", i don't know how speaking to the manager(me) is going to change anything. And when i tell you i'm the manager, do you really think you're going to accomplish anything by calling the owner? What's he supposed to say? "Oh i'm SO SORRY ma'am, those signs were just for show. PLEASE let me make it up to you by firing that mean ol nasty manager who read the signs I put up out loud to you".
